To make it easier for the public to choose energy efficient products, EMSD operates a Voluntary Energy Efficiency Labelling Scheme (VEELS) for household electrical appliances, gas appliances and office equipment. The scheme aims to save energy by informing customers of the energy efficiency performance of the products. The VEELS also intends to encourage product suppliers to make available more energy-efficient products to meet customer demand. Please refer to EMSD website for more details.
